They said "could mean." You changed it to "probably." Those are very different, i.e., "It's getting cloudy, that could mean rain" is not the same as "it's getting cloudy, it will probably rain." "Could be" acknowledges a possibility. "Probably" means more likely than not.

Yet another new argument. Missing the first turn is not the same as missing the first month.

Probably missing the first month when it's possible he could miss a lot longer is not a reason to attack someone and call them a liar. I don't appreciate it and it is very personal.
